- Pompe
- A device which converts mechanical force and motion into hydraulic fluid power.
- To excite the lasing medium. pumping addition of energy (thermal, electrical, or optical) into the atomic population of the laser medium, necessary to produce a state of population inversion.
- A device or machine that compresses and/or transports fluids, usually by pressure or suction, or both; may be used to remove water from a construction site or to convey water from one elevation to another.
- A machine which forces liquids or air into or out of something verb to force liquid or air along a tube the heart pumps blood round the body. the nurses tried to pump the poison out of the stomach.
- Помпа, насос
- A well-known machine used for drawing water from the sea, or discharging it from the ship`s pump-well.—chain-pump, consists of a long chain, equipped with a sufficient number of metal discs armed with leather, fitting the cylinders closely, and placed at proper distances, which, working upon two wheels, one above deck and the other below, in the bottom of the hold, passes downward through a copper or wooden tube, and returning upward through another, continuously lifts portions of water. it is worked by a long winch-handle, at which several men may be employed at once; and it thus discharges more water in a given time than the common pump, and with less labour.—main pumps. the largest pumps in a ship, close to the main-mast, in contradistinction to bilge pumps, which are smaller, and intended to raise the water from the bilges when
- A device for moving, forcing, or lifting liquids; also, the act or process of moving such liquids.

Насос, русский
- (лат . antlia), созвездие юж. полушария.
- , устройство для напорного перемещения (всасывания, нагнетания) главным образом жидкости в результате сообщения ей энергии (кинетической или потенциальной). различают динамические насосы и объемные насосы. иногда насосом называют также устройства для сжатия или разрежения газов (напр., вакуумные насосы) и для перемещения материалов (цемента и др.) потоком газа.
- Машина для сообщения энергии рабочей среде. в зависимости от рода рабочего тела различают насосы для капельных жидкостей (насосы в узком смысле) и насосы для газов (газодувки и компрессоры). в газодувках происходит незначительное изменение статического давления и изменением плотности среды можно пренебречь. в компрессорах при значительных изменениях статического давления появляется сжимаемость среды.

Population, английский
- A definable set of individual units to which the findings from statistical examination of a sample subset are intended to be applied. the population will generally much outnumber the sample. in re-randomisation statistics the process of applying inference
- See stock.
- A collection of units being studied. units can be people, places, objects, epochs, drugs, procedures, or many other things. much of statistics is concerned with estimating numerical properties (parameters) of an entire population from a random sample of units from the population.
- A group or number of people living within a specified area or sharing similar characteristics (such as occupation or age).
- Население; народонаселение; генеральная совокупность (в выборочном наблюдении); популяция (биол)
- Население
- 1. the number of people living in a country or town population statistics show that the birth rate is slowing down. the government has decided to screen the whole population of the area. 2. the number of patients in hospital the hospital population in the area has fallen below 10,000.
- Популяция
- Население; популяция -
- Популяция. в клинических исследованиях совокупность субъектов, обладающих какими-либо одинаковыми признаками (пол, возраст, диагноз).
- Население; популяция
- Any group of individuals, usually of a single species, occupying a given area at the same time; groups of organisms with homologue (same) alleles. p. cycle: changes in the numbers of individuals in a population which repeatedly oscillate between periods of high and low density. p. density: allowing a mathematically precise reflection - pd. • absolute: pd = number of individuals/unit area or volume [1/m2] or [1/m3] • relative: pd allows only a simple comparison (pd <, =, >, ? etc.). p. dynamics: the variations in time and space in the sizes and densities of populations; distribution due to changing food resources - the stability of a population depends upon abiotic factors, intraspecific competition (density dependent), natality, mortality etc. p. ecology: the study of the variations in time and space in the sizes and densities of populations, and of the factors causing those variations. p. fluctuation: variations over time in the size of a population. p. growth: is zero, when the birth rate equals the death rate (see carrying capacity). nt+1 = nt + r nt, current number of individuals r = (natality + immigration) - (mortality+emigration) r, intrinsic rate of growth (see density) p. pyramid: a means of illustrating the age structure of a population diagrammatically, by placing the youngest age class at the base and stacking successive age classes above it. p. regulation : a tendency in a population for some factor to cause density to increase when it is low and to decrease nt, momentary number of individuals when it is high. n0, number of individuals at start
- Generally, a collection of individuals with common characteristics. in statistics, a potentially infinite collection of independent (->independence) units that include all units of a specified type with attention paid only to the agggregate (->aggregation) property of the collection. a sample of data drawn from this population is a subset of the units constituting this population and scientific generalizations from such samples are limited by the size of the population originally specified (->model, ->representation).
- The process of scanning content to compile and maintain an index.
- Fish of the same species inhabiting a specified geographic area.
